Linux device driver for USB WIFI needs integrating

Linux device driver for USB WIFI needs integrating

[Chris Ward]

There is a Linux driver here
http://www.asus.com/Networking/USBN10_NANO/HelpDesk_download/ that needs
integrating into the 'kernel.org' source. Please can you pass this to
whoever should do this.

Do we need formal permission from ASUS, or do we just take it ?

Please cc: me on any replies as I am not subscribed to the LKML.

Thanks !

Isn't that device supported by the in-tree RTL8192CU/RTL8188CU driver?
(CONFIG_RTL8192CU, drivers/net/wireless/rtlwifi/rtl8192cu/)

If it isn't, it should only be a matter of adding the USB Id of the
ASUS device.

> Do we need formal permission from ASUS, or do we just take it ?

AFAICT the archive ASUS has made available contains a driver authored
by RealTek, so that would be where to ask.

The source files contains a statement that they are covered by GPLv2,
so formally you would not have to ask - although I'd consider it in
good taste to do so.

I just got a trap when booting the current OpenSUSE kernel (in the

lsusb shows
Bus 003 Device 024: ID 0b05:17ba ASUSTek Computer, Inc.

I've just built the OpenSUSE kernel from source, it has that CONFIG=m .
I think ASUS have changed the chip set.

Do we have to wait for ASUS to debug their driver ? Supposedly it worked
with an older kernel (up to 3.10 I think)

only the USB id AFAICT - 0b05:17ab is supported

does the attached trivial patch help?

I just realised that the above USB id was already added to the
in-tree driver - it should appear the next Kernel release.
(commit 9374e7d2fdcad3c36dafc8d3effd554bc702c4b6 in Linus' tree)

If my patch (which does exactly the same as the above) works for you
we can ask for that commit to be added to the stable kernels, so please
let us know how you proceed.

No, with the patch the device isn't recognised at boot time.

Strange.

Does the module 'rtl8192cu' get loaded automatically (check with  
'lsmod')?
What happens if you wait until the system is booted, then plug the  
device?

Could you put your '.config' and the output from 'dmesg' and 'lsusb -v'  
(with the device plugged in) on a server somewhere and post a link here?
(If not, send me the files in a private mail, then I'll post the  
relevant parts on the list)

Cheers
Anders

Re: Linux device driver for USB WIFI needs integrating

[Chris Ward]

I have put the requested files in http://tjcw.freeshell.org/usbn10/ . The
ones with 'after' in the name are with the device plugged in at boot.
There is also a Belkin WiFi adapter plugged in , because I need networking
active in order to write this email.

Cheers !

well, .config contains

so the driver is built.

and dmesg contains
> usb 3-2: new high-speed USB device number 2 using xhci_hcd
> usb 3-2: New USB device found, idVendor=0b05, idProduct=17ba
> usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
> usb 3-2: Product: 802.11n WLAN Adapter
> usb 3-2: Manufacturer: Realtek
> usb 3-2: SerialNumber: 00e04c000001
so the device is recognised (at USB level).

The module 'rtl8192cu.ko' isn't loaded as expected, however.

Perhaps it wasn't installed correctly - the USB id should have an entry  
in /lib/modules/3.16.7-21/modules.alias of the form 'alias  
usb:v0B05p17BAd*dc*dsc*dp*ic*isc*ip*in* rtl8192cu'
('grep usb:v0B05p17BA /lib/modules/*/modules.alias' should show it)

If the entry is missing, it must appear after the alias file is  
regenerated (with 'depmod -a').

If it's there, but the module is still not loaded when you plug the  
device, please try to load it manually (with 'modprobe -v rtl8192cu  
debug=5') and check dmesg again.

Cheers
Anders

There is this

Re: Linux device driver for USB WIFI needs integrating

[Chris Ward]

With the patch actually applied, the WiFi adapter is recognised and works,
both on boot and if the adapter is plugged in later. So, all is well.

What mainline kernel level will contain the patch ?

Thanks !

glad to hear that - and thanks for testing!

Marek (CC'ed) added the USB ID some 4 weeks ago, so it's scheduled for  
the upcoming 4.1

@Marek: can we get your commit 9374e7d2 added to the stable kernels,  
please?

Feel free to apply for stable. I also tested the patch on Linux 3.10.5x
so it ought to work all the way back to at least 3.10.

Please note that there are two commits just added to the mainline repo that 
should be propagated to all stable kernels. Both are addition of new USB IDs for 
an old driver, thus they will cause to side effects. Unfortunately, the Cc to 
stable was missed in the first of these, thus the need for this message. The 
second was Cc for stable, but I include it here for completeness.

The two commits in question are

FYI yesterday Marek's patch was accepted into the stable queues (3.10.x, 
3.14.x, 3.19.x and 4.0.x), so it will probably hit most distros in the next 
few weeks.

There is a Linux driver here
hxxp://www.asus.com/Networking/USBN10_NANO/HelpDesk_download/ that needs
integrating into the 'kernel.org' source. Please can you pass this to
whoever should do this.

Do we need formal permission from ASUS, or do we just take it ?

Please cc: me on any replies as I am not subscribed to the LKML.

Thanks !

With an out-of-tree driver you are on your own, sorry.

Did you enable the in-tree driver (CONFIG_RTL8192CU)?
(That driver supports the chip used by the ASUS device AFAICT)

What is the USB Id of the ASUS device (as shown by 'lsusb')?

glad to hear that - and thanks for testing!

Marek (CC'ed) added the USB ID some 4 weeks ago, so it's scheduled for  
the upcoming 4.1

@Marek: can we get your commit 9374e7d2 added to the stable kernels,  
please?
